SWING-LETREE-CLIP.

Specification of Letters Patent.

Application filed November 27, 1918. Serial No. 264,398.

To all whom it may concern:

Be it known that I, DAVID F. LAING a subj ect of the King of England, residing at Mc- Donald Hills, in the Province of Saskatchewan and Dominion of Canada, have inventcontracts, thus reducing its, cross-sectional dimensions so that the clip would otherwise become loose, this contraction may eifect a tight hugging of the bosses, thereby holding the clip firmly in position.

To the exact construction in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual re duction to practice may suggest, in so far as such changes or alterations are comprehended in spirit by the annexed claim.

In the accompanying drawings:

Figure l is a perspective View of the end of a swingle tree showing the improved clip attached thereto.

Fig. 2 is a longitudinal section of the structure of Fig. 1.

. Fig. 3 is an elevational view of the clip detached from the swingle tree and looking in the opposite direction as Viewed in Fig. 1.

Referring to the drawings, there is shown one end of a swingle tree 1, the improved clip B being attached at the extremity of this end. The improved clip comprises the usual band 2 in surrounding relation to the swingle tree and carrying the usualhook 3 provided for the attachment of the trace. The band 2 further than carrying the hook 3 is provided on diametricallyoppositesides with the laterally extending ears 4:, each carrying a boss 5, so that the two bosses face each other. In

the attachment of the band 2 to the swingle tree, the latter is counterbored to provide pockets in which the bosses 5 may rest. The

whole is further secured to the swingle tree o i by a bolt 6 passing through appropriate holes formed in the ears 4 and bosses 5 and a transverse hole formed in the swingle tree 1 in alinement with the aforesaid hole.

So long as the swingle tree 1 maintains its normal size, the band 2 will hug it tightly, but should the swingle tree shrink, as is likely to be the casein very dry weather, the

Patented Sept. 14, 1920.

band 2 cannot hug the swingle tree so tightly and would, therefore, but loosely engage the swingle tree, were not the bosses 5 provided. These bosses 5 set in the counterbored portions are tightly hugged by the circular walls of the c'ounterboredportion whenthe swingle tree shrinks and, therefore,

the band2 is held in tight engagement with I the swingle tree despite the shrinkage or contraction thereof.

.In attaching the improved clip to a swingle tree, the two ears 4 may be bent outwardly with reference to the band 2, so that the bosses 5 may not interfere with the at tachment of the band, the arms 4 being bent back in place when the bosses engage in the counterbored portions and the bolt 6 is attached. r

The invention havingbeen described, what is claimed as new and useful is: V

The combination with a swingle treeformed with counterbores on diametrically opposite'sides and inset from its end, of a clip attached to the swingle-tree in surrounding relation to the end portion of the latter v and provided with trace attaching means and formed with laterally projecting ears overlying the counterbores and formed with bosses disposed in the counterbores, and a bolt passing through the ears, through the bosses andthrough the swingle-tree.

Intestimony whereof I aflix my signature. v

DAVID LAING.
